Overview:
UBE2U, or Ubiquitin-conjugating enzyme E2 U, belongs to the ubiquitin-conjugating enzyme family. In the global yeast two-hybrid (Y2H) screens to study the specificity of interactions between catalytic domains of the human E2s with RING-type E3s, the analysis showed the UBE2U had a high-quality and physical interactions with a few E3 ligases (1) and (2).
Gene Aliases:
RP4-636O23.1

植物材料 用最精确的方法,称取不超过100mg的植物材料,置于处理过的研钵,加入液氮进行研磨 将研磨得到的粉末,快速转移至无RNase,并经过液氮冷却的2mL离心管(自备),
但是,这样做的前提的,RNA提得要好,浓度要高,这样免得RNA降解到不能用了。因为在有二价阳离子的(DNAseI buffer含有)情况下,RNA在60度以上时必然发生非酶促降解。
想搞清一个问题,如何区别是因为small RNA 引起的调控呢?还是tRNA引起的调控,有没有有效的分离这两种RNA的办法呢?
样品处理:
a. 植物组织:取新鲜或-70℃冻存100mg组织在液氮中研磨,把粉末加入到1ml裂解液中混匀。
b. 动物组织:取新鲜或-70℃冻存100mg组织加1ml裂解液,用组织研磨杵或匀浆器匀浆处理。
c. 贴壁细胞:直接在培养板中加入裂解液裂解细胞,每106细胞加1ml 裂解液。用取样器吹打混匀。
